The Toyo Proxes RA1 is a specialized autocross and racetrack tire that combines durability, consistency, and superb traction under dry or wet conditions. Its soft treadwear 100 compounds are performance-oriented to break lap times on racetracks worldwide. The tire is molded into a symmetric stepped tread design with an 8/32'' tread depth, delivering competitive performance and handling. The dry traction of the tire gets favored by the remarkable 6/32'' tread depth. At the same time, lateral grooves disappear at 4/32,'' and the maximum wet performance develops at 3/32,'' where only two central circumferential grooves remain.
The Toyo Proxes RA1 is the best street-legal circuit tire setup for those seeking quick lap times and optimal performance inside and outside the track. Its internal structure features a competition-modified radial build for extreme cornering and straight acceleration, guarantying maximum stability and response. Its optimal operating temperature ranges from 160 to 220 degrees Fahrenheit, with a hot inflation pressure of 30s high and 40s low PSI.
